英文:
Should I send X-expressions over the wire, or should I compile down to XML
问题
I'm writing a program that will send something similar-ish to HTML over the internet. The way my program represents the data is through X-expressions.
我正在编写一个程序，它将在互联网上传输类似于HTML的内容。我的程序通过X表达式来表示数据。
Should I send the raw X-expression over the wire, or should I convert it to XML and then send? Do I lose any fidelity from going from one structure to the other?
我应该将原始的X表达式传输到网络上，还是应该将其转换为XML然后再传输？从一个结构转换到另一个结构会丢失任何精确性吗？

除了由Barmar提供的评论中所给出的答案：
> 你可以使用内置的read函数
以及特别是由Kaz提供的答案：
> 这是有很大好处的，因为S表达式保留了类型信息。它们区分了列表和向量，字符串和字符以及符号，还有数字；浮点数和整数。一些Lisp语言具有循环符号表示法，以便可以序列化图结构。XML只是切割、嵌套的文本，没有含义。JSON只有字符串、浮点数、向量、字典（"对象"）以及一些符号，如true、false和none。
您还可以选择使用racket/fasl二进制格式来传输S表达式。它具有比write和read更快的加载速度和更小的大小，但不能直接人类可读。
英文:
In addition to the answers given as comments by Barmar:
> you can use the built-in read function
and especially by Kaz:
> There can be a great benefit, because S-expressions preserve type information. They distinguish lists from vectors, strings from characters from symbols, from numbers; floating point from integer. Some Lisps have a circle notation so that graph structures can be serialized. XML is just chopped up, nested text with no meaning. JSON has only strings, floating-point numbers, vectors, dictionaries ("objects")., and a few symbols like true, false and none.
you also have the option to use the racket/fasl binary format to transmit S-expressions. It offers faster loading and smaller size than write and read, at the cost of not being directly human-readable.
